Just Accepted “Just Accepted” manuscripts have been peer-reviewed and accepted for publication. They are posted online prior to technical editing, formatting for publication and author proofing. The American Chemical Society provides “Just Accepted” as a free service to the research community to expedite the dissemination of scientific material as soon as possible after acceptance. “Just Accepted” manuscripts appear in full in PDF format accompanied by an HTML abstract. “Just Accepted” manuscripts have been fully peer reviewed, but should not be considered the official version of record. They are accessible to all readers and citable by the Digital Object Identifier (DOI®). “Just Accepted” is an optional service offered to authors. Therefore, the “Just Accepted” Web site may not include all articles that will be published in the journal. After a manuscript is technically edited and formatted, it will be removed from the “Just Accepted” Web site and published as an ASAP article. Note that technical editing may introduce minor changes to the manuscript text and/or graphics which could affect content, and all legal disclaimers and ethical guidelines that apply to the journal pertain.

Abstract

2

Plasma strawberry anthocyanins were characterized in overweight (BMI: 26 ± 2 kg/m2)

3

adults (n=14) based on meal timing. At each visit, subjects ingested 3 study drinks: two control

4

and one strawberry drink. A strawberry drink was given at either 2 h before the breakfast meal

5

(BM), with the meal (WM) or 2 h after the meal (AM) and control drinks were given at the

6

alternative time points. Plasma anthocyanins and their metabolic conjugates were assessed

7

hourly for 10 h using triple quadrupole liquid chromatography mass spectrometer. Maximum

8

concentrations (Cmax), area under the curve (AUC) and bioavailability of pelargonidin-based

9

anthocyanins determined from the main conjugated metabolite (pelargonidin glucuronide) were

10

greater when a strawberry drink was consumed 2 h before the meal (BM) compared to

11

consumption WM or AM (p
